hi, i'm looking for a car kit for my iphone 4. it has to - play music/calls over fm and have good sound quality- charge the phone- plug in via the cigarette lighter- be hands free- work with iphone in protective rubber case- have a longish arm (my car cig lighter is low and kind of hidden)

bonuses- perfect fit, just "snap in" without having to close arms (like those cheap cradles from $2 stores)- connect via bluetooth (ie hands free still works without iphone being plugged into cradle)- only one connection required, doesnt require a line input from the headphone jack.

closest thing i've found is a [url=http://www.belkin.com/pressroom/releases/uploads/06_01_09TuneBaseDirect_TBFM.html]Belkin TuneBase FM with Handsfree for iPhone[/url].

but that requires a input from the headphone jack. other than that its nearly perfect.

there are a lot of cheap things on trademe, just wondering if anyone has found the perfect cradle?

I use a http://www.dealextreme.com windscreen mount cradle, and a cig plug belkin tunecast fm transmitter/charger. Also Bluetooth earpiece. Mostly used for gps duties, hardly take calls so works ok for me.
You may be better to start looking at compatible head units with USB/Bluetooth connectivity.

I think for hands-free you will have to plug the 3.5mm jack into the headphone jack because Apple didn't allow that feature?But I do know some BMWs have that cradle without the need of a headphone jack but I don't know if that works in tangent with bluetooth.

purchased the belkin fm with hands free, but the one i got was a dud, so have to take it back for a replacement.

the mic didnt work properly and other call just heard a constant beeping sound (and not my voice), was able to get them to hear me perfectly if i only partially plugged in the plug in the headphone jack, but then i couldnt hear them at all through my stereo. tried it in two cars, same result.
